Celmet™ Metal Foam

  • Celmet™ is a family of porous metals that have a three-dimensional network structure. In addition to nickel (Ni), alloys such as nickel-chrome (Ni-Cr) and nickel-tin (Ni-Sn) are also used to make Celmet™.
  • Applications of porous metals include positive electrode current collectors for nickel-metal hydride batteries for hybrid vehicles, fuel cell components and electrodes for hydrogen generators, thereby substantially contributing to energy saving and reduced environmental burden.

Superconducting Wires

  • High-temperature superconducting wire, which can be used at the temperature of liquid nitrogen, will either be bismuth-based or rare earth-based.
  • Sumitomo Electric’s DI-BSCCO™ superconductor is an innovative bismuth-based superconductor that utilises its advanced technologies such as overpressure sintering.
  • Providing a good balance among its world-leading performance, high quality, and price, this wire has been selected to be used in industrial products and R&D projects.
  • Not only does Sumitomo Electric supply this wire, but it also gives demonstrations and develops products applying superconductor technology with the aim of contributing to the creation of an advanced society.

Redox Flow Batteries

  • The redox flow battery is a storage battery that uses ionic
    reduction/oxidation reactions for charging and discharging
    electricity.
  • Long-life and highly safe, it is considered to be an
    indispensable technology for promoting the introduction of
    renewable energy such as solar and wind power.
